Hmm, I have my HIRES mod cfg set to 1440x900 and is working ok since the whole wide screen is displayed and the cursor disappears at the bottom and right, I enabled your mod Rubini & file goes in it's correct spot but no change, 3D view is still stretched, rotating antenna is still oval shaped.

A file compare shows that your Cameras.dat is the correct one. This is strange, I will try a different setting, 1680x1050, might try at 1024x768?
Edit: Ok I tried the above even removed the HIRES mod but no change, everything is stretched, what am I doing wrong?
Also I am running ATI Tray Tools, not running the CCC, don't know if this should effect it!
